To .all whomj may concern:

Be it known that I, Josera Jannie-wais, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecount-y of Kings and State of New York, have invented a new andImprovedV Dumping-Vehicle, ofjwhich the following is a full, clear, andexact description.

My invention relates to a dumping vehicle, particularly adapted for thetransportation of asphalt. y

An object of my invention is to provide a street truck which may be usedas is usual with trucks of this character and vwhich may be convertedinto anC open bottom truck for the discharge of material carriedby acart mounted thereon. l j

A further object of my invention is to provide a vehicle of theabove-indicated character having an improved means for dumping thematerial from the cart, which means is disposed adjacent the driversseat.

Reference is to be had to the accompanying drawings, forming a part ofthis speciof reference indicate corresponding parts in all the figures,and in which- Figure 1 is a side elevation of my improved vehicle, partsof the truck being broken awayto show the track and showing the dumpingmechcanism in two parts; Fig. 2 is a plan view looking down upon thetruck shown in Fig. 1 with the cart and part of theilooring removed; andFig. 3 1s a longitudinal vertical sectional view taken through-'the cartand showing the reverse side of the dumping mechanism to that' shown inFig. 1.

Described more in detail, I have shown a street truck A ot' any suitableconstruct1on,-hav1ng a drivers seat B extending some material distanceup from the front end thereof, mounted below which drivers seat is aVhoisting drum C, asis common with devices of this general character.This truck has a pair of parallel longitudinallyextending tracks D,mounted between which tracks isa removable floor E, in this casev shownto comprise two planks projecting from the front end of'each of which isa lug-F adapted tov engagebeneath a front floor board Gv, in order holdthe planks in position. It is to be understood that when the device isused as an ordinary truck,

these planks will remain in place, but when the device is used as adumping vehicle, these planks are removed.

Mounted to roll on the tracks D from the fiat railroad cars, is a cartH, adapted to be drawn on the track by means-of the drum C. This cart Hhas a cover J, flanged Wheels K, and a downwardly-dropping twopartbottom L, which bottom is drawn into closed position by means of a chainconnection 4, as is common with devices of this character. One end ofthe chain 4 passes about a drum 5 extending transversely through thefront of side plates 6 of the cart H. Rigidly mounted upon the righthandside of the drum 5 and on the outside of the adjacent side plate 6, is aone-way ratchetvwheel 7, the actuation of which in a clockwisedirection, will wind up the chain 4, to close the trap doors forming thebottom L.

Loosely mounted on the drum 5, abutting the ratchet wheel 7. and on theouter side thereof, is an actuating lever 8, the Yforward arm 9 of whichis bent slightly upward and extends forwardly, so that the handle 10 ispositioned to one side of and slightly in advance of the drivers seat B.

Pivoted to the rear end of the short arm or rearward extension 11 of thelevel' 8 is a forwardly-extending feeding arm 12 extending above thelever 8. This arm 12 has va downwardly-extending tooth 13 adapted tofall by gravity into Athe notches of the wheel 7, to feed said wheel ina clockwise direction when the handle 1() is oscillated over alimitedare of movement by the y operators hand. Slightly in advance of thetooth 13 and projecting inwardly from the feeding arm 1Q, is a pin 14adapted to move in a recess 15 in the under side of a pawl 16 pivoted at17 to a bracket 18 mounted on the adjacent side plate G. Projectingdownwardly from the pawl lt, is a projection 19, one end of whichconstitutes a hook torming the forward boundary of the recesl5 and whichlimits the movement of the pin 14 in the recess 15 and the opposite endof which forms a tooth 20 adapted to engage the ratchet-'wheel 7 inorder to hold tho same, to prevent it from rotating in acounter-cloclm'ise direction.. The curved face 21- of the projection 19permits the teeth of the ratchet wheel 7 lo raise the pawl 16,therebyforming a means b v which the trap doors forming th(` bottom lmayatk be brought linto closed position when the handle 10 is oscillatedbythe driver while seated on the seat B. The doors forming the bottom willdrop of their own weight, when the'teeth 13 and 20 arel disengaged fromthe ratchet 7.

It will be noted that the forcing of the lever arm 9 downward for amaterial distance, as shown in dotted lines in Fig. 1, will cause thepin to engage the projection 19, raisingthe awl 16 on its pivotal point17, thereby lifting the tooth 20, to clear the ratchet 7. YSimultaneously with this action of the pin, the aforesaid hook willcarry the pin upward around the point 17 as a center, causin the tooth13 to leave the ratchet. By this construction, the oscillation of thearm 9 through a limited arc, will wind up the chain 4, to close thebottom, but an exaggerated downward movement of the arm 9 will unlockthe ratchet 7, thereby ermitting the doors tio automatically open otheir own weight, it being noted that the entire operation may beerformed by the driver without leaving t e-seat B.

As shown most clearly in Fig. 3, the feeding arm 12 is provided witha'rigid finger 12 which extends across and embraces the pawl 16, and theforward end of the feeding arm 12 is provided with a handle 12".

ln further explanation of the operation of this invention it will benoted that when the lever 8 is oscillated, as above described, by the oerators hand for the purpose of rotating t ie drum to close the bottomof the cart, the teeth 13 and 20 engage the ratchet wheel as described,but the pawl 16 will not be lifted out of engagement by the in 14 whilethe lever is thus being operat under "ordinary conditions because theextent of movement of-the handle 10 would not be so far downward as toenable or permit the operator while grasping it with his hand to unlockthe pawl 16. After the cart bottom has been closed in the mannerdescribed, the operator will oscillate the lever 8 both upward andrearward, causing the handle 10 to stand substantially vertical, thefeeding arm 12` of course, following the extension 11, bringing thefinger 12 substantially into engagement with the upper part of the pawlnot far distant from the pivot 17. The tooth 13, however, will be inengagement with one of the teeth of the ratchet wheel, thus holding thelever 8 and feeding arm 12 in the position last described during thetransportation of the cart. The purpose of the finger 12', therefore, atthis time, is to limit the upward oi' rearward swing of the lever 8.Another function of 'said finger, however, is to )reveut the accidentaldisplacement of tlie pawl from the ratchet wheel. as is so common inthis class of mait isdesired for the man on the seat B to dump the load,he will grasp the handle 12", lifting the tooth 13 out of engagementwith the ratchet wheel, 'and thereby swing the lever 8 forward aroundthe axis of the drum until the lpin 14'reaches t-he hook formed at theforward end of the recess 15 in the pawl 16. This position of the lever8 will bring the handle end of the lever opposite the op- Ierators footat which-time he will kick said handle end withhisfoot downward,throwing either or both teeth out of engagement with the ratchet wheeland said teeth will so remain out of engagement until the operatinglevers are returned to the operating position by the operator graspingone or the other of the handles 10, or 12A preferably the latter.
